An iOS bug caused iPhones to crash when the date changed to December 2

An iOS 11 bug caused some iPhones to crash when the date changed to December 2.

Apple rushed out a fix for the bug in a software update early Saturday.

It's the second major Apple software bug this week.

A bug in iOS 11 caused some iPhones to crash early Saturday as the calendar changed to December 2. According to iMore, the bug was related to notifications from third-party apps.

Apple has already issued a fix. It pushed out iOS 11.2 to devices early Saturday morning ahead of its scheduled release early next week. In addition to fixing the "December 2" bug, iOS 11.2 also adds peer-to-peer payments through Apple Pay, which lets you send money to other iOS users through iMessage. (Think of it as Apple's answer to Venmo.)

But since the iOS 11.2 software update was released early, peer payments won't be live until Monday or Tuesday. It'll only be available in the United States for now.
